开花植物挥发性有机化合物（VOC）排放的时间往往与传粉者觅食活动相吻合。挥发物排放通常被认为是由环境变量，如光强度，和/或昼夜节律。问题是，传粉者自己在多大程度上提供了关于它们存在的信息，以与它们与开花植物的长期共同进化保持一致。大黄蜂是带电的，并提供电刺激时，访问植物，通过去极化的电位在茎的花朵。在这里，我们测试的假设，即觅食熊蜂的电荷增加蜜蜂授粉植物的花挥发性排放。我们调查了两种蜜蜂授粉的植物（矮牵牛和金鱼草）暴露在典型的觅食熊蜂的电荷的VOC排放量的变化。P. integrifolia稍微增加其行为和生理活性化合物的排放量，以响应觅食的熊蜂的访问，平均呈现121 pC的电荷。我们表明，对于P. integrifolia，强电刺激（600-700 pC）促进挥发性排放增加，但当使用更能代表飞行传粉者（100 pC）的较弱电荷时，没有发现这一点。A. majus不受强电荷（600-700 pC）或弱电荷（100 pC）的影响。这项研究开辟了一个新的研究领域，即飞行昆虫的电荷可能提供信息的存在和植物的传粉者的物候。作为电感受的一种形式，这种感觉过程将具有适应性价值，使植物能够更好地确保当潜在的受体存在时，它们有吸引力的化学信息被释放。在线版本包含补充材料，可通过10.1007/s 00114 -021-01740-2获得。
The timing of volatile organic compound (VOC) emission by flowering plants often coincides with pollinator foraging activity. Volatile emission is often considered to be paced by environmental variables, such as light intensity, and/or by circadian rhythmicity. The question arises as to what extent pollinators themselves provide information about their presence, in keeping with their long co-evolution with flowering plants. Bumblebees are electrically charged and provide electrical stimulation when visiting plants, as measured via the depolarisation of electric potential in the stem of flowers. Here we test the hypothesis that the electric charge of foraging bumblebees increases the floral volatile emissions of bee pollinated plants. We investigate the change in VOC emissions of two bee-pollinated plants (Petunia integrifolia and Antirrhinum majus) exposed to the electric charge typical of foraging bumblebees. P. integrifolia slightly increases its emissions of a behaviorally and physiologically active compound in response to visits by foraging bumblebees, presenting on average 121 pC of electric charge. We show that for P. integrifolia, strong electrical stimulation (600–700 pC) promotes increased volatile emissions, but this is not found when using weaker electrical charges more representative of flying pollinators (100 pC). Floral volatile emissions of A. majus were not affected by either strong (600–700 pC) or weak electric charges (100 pC). This study opens a new area of research whereby the electrical charge of flying insects may provide information to plants on the presence and phenology of their pollinators. As a form of electroreception, this sensory process would bear adaptive value, enabling plants to better ensure that their attractive chemical messages are released when a potential recipient is present.
